Inventor: WYLES RICHARD H
IPC: H04N5/374
Filed: 1990-03-22
Abstract: A readout circuit for use with a focal plane array that employs a single tran­sistor in each unit cell and a single capacitive feedback transimpedance amplifier to process the outputs of each column of detector elements of the array. The capacitive feedback transimpedance amplifiers extract the signals associated with the pixels along a particular row of the array. The present invention permits high performance readouts to be constructed with very little circuitry in the unit cells. Only a single minimum sized transistor switch is required in each unit cell to perform readout and reset functions for the array. In the disclosed embodiment, the readout circuit com­prises an array of unit cells, each cell comprising a detector input circuit, a single transistor and a single charge storage capacitor. Row address circuits are coupled to the cells in each row of the array. A plurality of capacitive feedback transimpedance amplifiers are coupled to the cells in each column of the array. The amplifiers pro­cess charge derived from the detector elements and stored in the charge storage ca­pacitor of each unit cell. Column multiplexing circuits multiplex the output signals provided by each of the amplifiers. Column address circuits are coupled to the col­umn multiplexing circuits which couple output signals from each of the multiplexer circuits as the output from the readout circuit.

Abstract: In a circuit card assembly (10) for use within an information processor (computer) wherein the assembly includes a fiber optic connector assembly (13) as part thereof, there is provided means for enabling electrical connections (41) to be made to the circuit card's circuitry in the same area as the fiber optic connector's housing (15) so that charging of the card (to the potential of the mother board to which it will be coupled) can occur prior to coupling of the card to the board. Once the card is positioned and thus connected to the board, the charging means of the invention can be removed and a desired fiber optic connector inserted within the housing so that desired optical connections can be made with corresponding components (e.g., receiver, transmitter) which form part of the circuit card assembly. Both optical and electrical connections thus occur within the same housing.

Abstract: A branch prediction control circuit has a register. A main memory provides a machine language instruction to the register and an instruction buffer (101). The prediction control circuit decodes the instruction held in the register and predicts whether or not the branch is taken. If the instruction is a relative branch instruction, a sum of the address of the instruction and a displacement included in the instruction is computed to provide a branch address. A the same time, a branch address valid signal is provided. With this arrangement, reliable branch prediction of the relative branch instruction is realized with a small number of hardware.

Abstract: In a computer system, the flow of data from an execution unit (20) to a cache (28) is enhanced by pairing individual, sequential longword write operations into a simultaneous quadword write operation. A primary and secondary write buffer (50 52) sequentially receive the individual longwords during first and second clock cycles and simultaneously present the individual longwords over a quadword wide bus to the cache (28). During the first clock cycle, when the cache (28) is not performing the quadword write operation, it is free to perform the requisite lookup routine on the address of the first longword of data to determine if the quadword of address space is available in the cache. Thus, the flow of data to the cache 28 is maximised.

Abstract: The sub-rate channel carrying capacity and the efficiency of bandwidth usage are improved over the CCITT I.463 standard, for switching systems having a granularity, that is, the smallest channel size that can be switched through the system, of better than 64 Kbps (e.g. 8 Kbps). The system is capable of performing rate adaptation for multiple synchronized sub-rate channels in accordance with a predefined multiplexing protocol. The protocol calls for "time interleaved" multiplexed rate adaptation to be performed, i.e., multiple sub-rate channel data is packaged into fragment size envelopes (or integer multiples thereof). The width of a fragment is also matched (ideally equal) to the granularity of the system's switch. As a result of using the time interleaved multiplexed rate adaptation scheme, the rate adaptation process, the channel carrying capacity of the system at large, and the use of the system's switching and bandwidth capacity are all improved.

Abstract: A two-wire power and position control system uses a pair of electrical conductors 4 between a central station 4 and remote station 1, which is arranged to generate a physical displacement by a permanent magnet DC motor 6 and attached gear-linkage mechanism 7. Pulsating voltage is applied to the link 4 from the central station to the remote station as the power source for the DC motor. The physical displacement information of the remote station is extracted by the central station within the off-cycles of the pulsating power signal. The remove station enables or disables the flow of back-EMF signal generated by the permanent magnet DC motor as a means of position indication. In another arrangement, the remote station is arranged to sequentially connect various impedance to form part of a voltage divider, the change in impedance being used to affect a voltage derived from the voltage divider at the central station. In either arrangement, the central control station is capable of monitoring and controlling the position of the remote station.

Abstract: The present application describes an electrochemical metering apparatus that provides for convenient storage and presentation of the analytical electrode, simple assembly, and two calibration modes. The apparatus includes an electrode storage (50) and presentation assembly (30) that permits the user to introduce the electrode into a sample solution while simultaneously observing the meter's output (42), and store the electrode when not in use. All structural components are intended to fit together with interlocking tabs and windows. A serial port (77) fits within the construction of the main housing without the need for bolts, and battery clips (85) that depend directly from the circuit board obviate the need for wiring connections. Two calibration modes are featured. A "segment addition" mode permits separation of the voltage/concentration curve into individually plotted regions, the number of which depends on the number of reference solutions used in the calibration procedure. The segment corresponding most closely to the measured potential of a sample solution is used to calculate concentration. In an alternative calibration mode, one or more reference solutions are used to establish metered voltage/concentration combinations that are compared with expected, known values. Any discrepancies therebetween furnish a "noise level" value associated with the apparatus that can be used to more precisely define the orientation of the voltage/concentration curve.

Abstract: The power supply of electronic apparatus is controlled according to the operational state of a power on switch and a power off switch. A first detector detects that the power supply voltage falls below a first predetermined voltage and a second detector detects that the power supply voltage falls below a second predetermined voltage. A device produces the same operational state as that in which the power off switch is actuated in response to the detection output of the first detector and prohibits the operation of the power on switch in response to the detection output of the second detector. A predetermined protection process is performed when the power supply voltage falls below a prescribed voltage in which the supply voltage is compared with the two predetermined voltages to produce the same state as when the power on or the power off switch is put into a predetermined condition in response to the comparison result.
